3 Claims.

This invention relates to new-and useful improvements in feeds for oil burners and has particular relation to a fuel feeding means for kitchen range burners.

An object of the invention is to provide a continuously operating system for supplying oil to the type of burners commonly employed in kitchen ranges.

Another object is to provide afuel supply system of the character stated and which is of simple construction, including a minimum of parts, and which is reliable in operation.

Other objects and advantages willbecome apparent from a consideration of the following detailed description taken in connection with the accompanying drawing wherein a satisfactory embodiment of the invention is shown. However, it will be understood that the invention is not limited to the details disclosed but includes all such variations and modifications as fall within the spirit of the invention and the scope of the appended claims.

In the drawing:

Fig. 1 is an elevational view showing the complete system of the present invention;

Fig. 2 is a vertical sectional view on an enlarged scale through the motor and gear casing and pump of the invention;

Fig. 3 is a vertical sectional view on an'enlarged scale through a fuel level control means employed; and

Fig. 4 is an enlarged perspective view showing thepump operating means.

According to the present invention, fuel oil is pumped directly from a drum or tank Ill, in a II which may. be in a kitchen range or the like. The burners II are ordinarily fed from-an inverted bottle (not shown) which bottle is mounted on a stand (not shown) adjacent the burners and feeds oil to a valve 12 from which the oil passes to the burners through tubes 13. In the present instance, and usually, valve 12 is a multiple valve comprising a pairof needle valves having hand pieces l4. I

In the present instance, .valve I2 is fed from a fuel level control means l through a supply tube I6. Means 15 comprises a receptacle [1 having a fuel feed outletopening or port 18 to which the tube 16 is connected by any suitable fitting or coupling I9. By reference to Fig. 3 it will be noted that the receptacle I1 is open at its upper side and is hollow and that. the upper side is ordinarily closed by a cover 20 pivoted to the receptacle by a stem 28 about which it may tacle.

be swung horizontally so that the interior of the receptacle may be inspected. A pin 2| prevents casual movement of the cover. Further, it will be seen that the bottom wall of the receptacle includes a thickened portion 22, the upper sur- 5 face of which is considerably above the fuel feed outlet opening I8 and which thickened portion provides a shoulder 23 defining one side of a small section or compartment 24 of the recep- 10 An inlet opening orport 25 is provided in the bottom wall of the receptacle l1 and enters the latter in the section or compartment 24 and a fuel supply tube 26 is connected with this port 25 by a suitable fitting or coupling 21. Fuel oil 16 fed to the section or' compartment 24 through the tube 26 may obviously pass into the coupling l9 and thence into the tube It to be carried to the valve l2. The level control means I5 is equipped with a stem or post 28 and isadjust- 20 ably mounted by passing such stem or post through a. suitably located bracket23. Means ment is .such that when the fuel in the section or compartment 24 rises higher than the upper surface of the thickened portion 22 or the shoulder 23 formed by said portion the surplus oil will pass-out through an overflow or return port'3l and into a return tube 32 connected with said port by any suitable fitting or coupling 33 and having its discharge end 34 located within the tank I0.

The lower end of tube 26 is carried downwardly through the oil in the tank I 0 and has its extreme lower end 35 c'onnected with the discharge outlet c 36 of a pump 31. This pump 31 is carried at the lower end of a tubular column or length of pipe, 3B, the upper end of which is mounted in a thickened portion 39 of a casing 40. Casing 40 is in turn mounted on a coupling 4| which may be threaded into a tapped opening in the upper side of thetank 10 as shown in Fig. 1. Casing 40 includes a receptacle-like lower portion 42 and a cover portion 43 and the upper end of the column 38 extends into the casing and is isposed above the bottom wall of the receptacle portion 42 thereof.

threaded or otherwise secured to the lower end of the column 38 as shown' in Fig. 2 and within the said cylinder portion there is a plunger or piston 45 to which is connected a wire or rod '46 extending upwardly through the column and projecting at the upper end thereof. Within the lower portion of said column is a coil spring 41 bearing at one end. against the piston 45 and normally tending to keep it in a discharged position, and hearing at its other end against stop means 48.which may comprise a pair of pins extending transversely-through the column. A ball check 49 controlsthe oil entrance port 50 of the pump and a ball check 5| controls the discharge of the pump into the outlet '36. Preferably, a strainer 52 is located to prevent the entrance of particles of foreign matter into the pump.

Rotata'bly mounted on the upper end of the tubular column ,38 is a sleeve 53 on the upper por- I tion of which is a cam member 54 having a gradually inclined cam surface portion 55 and a sharply inclined cam surface portion 56. On the lower portion of sleeve 53 is a relatively large gear 51, and the sleeve in addition to being turnable about the upper end of the column rests on or bears against the enlargement 39 of the bottom or receptacle portion 42 of the casing 40.

By reference to Fig. 4 it'will be noted that the column 38 extends above the cam54 and vertically reciprocatable in the upper end portion of said column is a plug-like member 58 the upper end portion of which is kerfed and receives a portion of a member 59 extending transversely thereof and projecting beyond one side thereof. The projecting portion of the member 59 extends through a slot 60 opening through the upper end of column 38 whereby said member 59 and the plug-like member 58 are held against turning movement. Wire or rod 46 is carried upwardly through member 58 and then has its end passed through a slotted portion of the member 59 which slotted portion is pinched against the wire as at 61 whereby to secure it.

-Within the casing 48 is a motor 62 including a rotor 63 the vertical shaft 64 of which extends into a relatively long bearing 65 formed with the Preferably the lower portion 42 of the casing 40' I constitutes an oil sump whereby the shafts and gears .may be lubricated. The top wall I21 of the cover portion 43 of the casing is preferably provided with an opening closed as by a removable disc 13 to which is attached a hand piece 14 and the disc simply sets into a recess in the wall 12 and is held as by a flat spring I5 which spans the recess or opening and engages the under side of the wall at oppositesides of said opening.

Obviously, by flexing the spring the disc may be shifted to one side or the other of the opening and thenremoved to permit of inspection of the motor.

Assuming that the means of the present invention is completely installed and that .the level control means -|5 has been properly adjusted or adjusted to the proper elevation the motor 62 may be started and fueloil will be supplied to the valve l2 and from thence to either or both of the burners II as desired. Through the gears 66, 61,

- Hand 51 the motor will rotate the sleeve 53 and the cam 54 will be carried with the sleeve. In this connection it is noted that said cam may be formed integral with the sleeve or may be formed separately therefrom, and secured thereto. As the cam is rotated its gradually inclined surface 55 moves beneath the projecting portion of the member 59 gradually elevating said member and the plug-like member 58 and drawing the wire or red 56 upwardly thereby raising the piston or plunger 45 against the action'of the spring 41 and compressing the latter.

As the piston 45 is drawn upwardly fuel oil is drawn into the cylinder 44 through the port 50, the action of the piston causing unseating of thecheck valve 49 and seating of the check valve 5|. In this way, the pump is loaded or charged and as the cam continues toturn its sharply inclined surface 56 comes under theprojecting portion of member 59 or in other words the high point of the cam moves from under said portion of such member releasing the member so that the spring 41 may act to draw the-members 58 and 59 downwardly and project the piston 45 downwardly causing seating of the valve 49 and unseating of the valve 5lwhereby the pump dis-.- charges into the outlet passage 36 and thence into the tube 26.

As the pump continues to operate, tube 26 delivers the fuel into the section or compartment 24 of the oil level controlmeans l5 and from such compartment the required amount of fuel passes into the tube I6 for delivery to the valve l2 and thence to the burners. When the height of oil in compartment 24 reaches the flood stage, the surplus oil passes into the over-flow port 3| and thence to the tube 32 and is returned by such tube to the tank Ill. Tube 26 passes out of the tank and tube 32 enters the tank through a notch or cut-out 16 in one side of the coupling 4| as best shown in Fig. 2.

It is the-present intention that the motor 62 operate constantly and the capacity ofthe pump 31 is such that said pump may supply oil in excess of the maximum requirements of the bumers fed from the level control means l5. All surplus oil is returned to the tank through tube 32 and in the event that the burners are completely cut off and the motor is not stopped the entire out-put of the pump over-flows back to the tank. -,Since the system does not-require attention and since the motor 62 consumes very little current, 6 or 8 watts, there'is little advantage in shutting it off unless the burner is to be out of operation for a long period of time. As the projecting portion of'member 59 passes through the slot 60 in the upper end of the pipe section 58 it will be appreciated that said member will not turn with the cam but may only move vertically.

Having thus set forth the nature of my invention, what I claim is:

1. In an apparatus-of the character described, a coupling providing a detachable connection, a casing atthe upper side of and supported by said coupling, a column entering said casing and supported by said coupling andextending from the lower side thereof, a pump cylinder carried by the lower end of said column, a reciprocable piston in saidcylinder, means secured to the piston and extending upwardly through the column, a-
